To all whom it may concern:

Be it known that we, CLARENCE .f'LAR- SEN and JONAT AN SNYDER, citizens of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in Store-WVindow Structures, of which the fo'llowing-is a specification, reference being had to the accompanying drawings.

This invention relates to window structures and particularly to store fronts.

One of the'objects of' the 'invention i's to provide a construction of this character in which the window'sash or plate glass of the window is firmly, yet yieldably, held 'in place so asjto permit expansion and contraction of the plate glass" and of the allied parts. f

A further object is to provide means :for

V draining oif the moisture which condenses on the inner face of the seeker plate glass, said means permitting ventilation which, of course, tends to reduce the condensation of moisture, and a further object in this connection is to provide for controlling the effective size ofthe drainage openings bythe provision ofa shiftable dani'per.

-Still another object is [to provide :means which will permit-the greatly detachment of the sash when required and -'-the replacement thereof and means for supporting-the lower edge offthe sash on a cushion of yieldable material.

"Other objects will appear in the course of the following description.

Our invention :is illustrated in the accompanying drawings 'wherein'r Figure 1 :is a' fragmentary -elevationjo'f the lower portion or sill of a store window constructed in accordance with our invention;

Figure 2 is a section on the line 2-2 of Figure 1; e V

Figure 3 is a section on the line 3-3 of Figure 1;

Figure 4 is a @fragmentary perspective View of the window sill and-allied parts.

:Referring to these drawings .10 designates the window sill proper and'l-l-thesash; stop mounted upon the window-sillzin any suitable manner. This sash stop has a width less than the-widthof'the windowsillso as to provide a vertically extending shoulder inward of the "face'of the window sill. The

upper face of the stop is longitudinally cutaway ad jacent the front of :the stop to form a gutter.

Extending :overthe upper face of the stop 11 an'd'into said gutter downward ,over the side of the shoulder and o ver the upper face of the window sill lea-sheathing, designated generally at 12, of thin sheet :metal. "This is formed so asto providea horizontal portion 13, a downwardly and 'inwa rdly extending overhanging portion 14, ,a downwardly a nd' forwardly extending portion 15 which constitutes the bottom of the gutter, a downwardly extending portion 16 which constitutes the face of the shoulder, and a horizontal portion 17 which extends ove-r the upper face of the window sill beyond the shoulder. Preferably this metal sheathing is extended downward over the front face of the'window sill, as at 18, and as il lus'trated this front face is formed'with two longitudinally extending beads 20'. "This sheet sheathing 12 may be attached to the faces of the window 'sill' a'nd stop in any suitable manner;

Resting upon the horizontal portion 17 and disposed against' the shoulder 16 are a plurality of longitudinally extending channeled blocks 21. These are spaced from each other to provide openings between the blocks'a's best shown in Figure '1'. Resting upon the series of supporting blocks 21 is a cushion'22 which is preferably made of rubher or other material maybe used; The downwardly extending face-16 of the metal sheathing 12 is formed at intervals with the drainage ports or channels 23 which converge downward and terminate at the horizontal face 17 of the sheet. Disposed upon "the portion 15 of the sheathing 12 or, in other words, dispo'sed inthe gutter or channel formed' loy cutting away the upper face of the stop 11 is a damper plate 2 1- which is sufficiently shorter than the total length of the channel 15 to permitthe damper plate to be shifted longitudinally. This damper plate at its rea'r'edge has an'upwardly and forwardly extending iflange :fitting against the overhanging shoulder 14: and the damper plate is also formed at intervals with ports '26 adapted to register with "the ports :23 when the damper plate isshifted into one position. Obviously th'e damper plate may be shifted to carry these openings 26 entirely outofre'gi'ster orpa-i tially into register and thus the effective area of the drainage ports may be c0ntrolled.

For the purpose of holding the sheet of plate glass 29 in place we provide a sheet metal 'molding 27 whose upper edge is up wardly flanged, as at 28, to bear against the glass 29 While its lower edge rests upon the horizontal portion 17 of the sheathing 12 upon the exterior of the glass. In order to hold the molding 27 in place we provide the wood screws 30 which pass through the molding at intervals and extend through the cushion 22 and are engaged with expansible anchoring members 31 of any ordinary or suitable form which are embedded in the stop 11. The lower edge of the molding 27 is provided at intervals with outlet ports 32 which are in alignment with the channels or ports 23 and with the spaces between the supporting blocks 21. Thus it is obvious that any water which may collect upon the plate glass 29 and run down into the channel 15 will, if the damper plate 2 1 is shifted to open the ports 23, run down onto the portions 17 and pass out. between the blocks 21 and out through the drainage openings 32 and obviously these openings 32, the spaces between the blocks 21 andthe channels 23 will permit ventilation of the interior of the window thus tending to reduce condensation.

While we have heretofore described a structure in which metal sheathing is carried down over the face of the sill 10, we do not wish to be limited to this as the apron 18 which extends down over the face of the sill may be omitted and the portion 17 may terminate at the upper face of the sill. This is particularly desirable where the window sill is of stone or where the construction illustrated in Figures 2 and 3 is used at the jambs of the window. While we have illustrated a construction which is particularly adapted for the sills of store or display windows, it is obvious that the same construction might be used for the jambs of the window, this construction permitting ventilation. I

The sheet of plate glass 29, which is subiected to considerable strain by reason of expansion and contraction, is yieldably supported not only by the cushion 22 but by the sheet metal molding 27 and the upper flange 28 of this .molding engages the margin of the window beyond the point of engagement of the shoulder 16 with the plate glass. Thus while the plate glass is firmly clamped in place a certain amount of yielding movement is permitted which will tend to prevent the glass from being broken under wind pressure or other stresses and which will permit not only expansion and contraction of the glass itself but of the, metal framingparts. While we do not wish to be limited to any particular material, we have found that sheet copper is preferable for the sheathing 12 and for the molding 27. Obviously, the structure might be changed in many Ways without departing from the spirit of the invention as defined in the appended claims.

l/Ve claim 1.
